- Know where you are, there is a good Wuxi, if necessary, can be introduced to you
- Q: Standard grade two grade coke standard
- Quality index of cokeCoke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
- Q: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
- Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press
- Q: Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilizationCa3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O (P), phosphorus, phosphoric acid and CH3OH, the following process raw materials comprehensive utilization rate is high, less waste(1) in the reaction, which belongs to the replacement reaction is ______[optional: (I), (II) and (III), (IV), (V).(2) chemical reaction equation II under high temperature of ______; solid waste can be used for ______.

(VI) in this part of the industrial production(6) written by P H3PO4, the reaction of the ______ ______.
- The answer is: Ca3 (PO4) 2+5C+3SiO2High temperature.?3CaSiO3+2P+5CO =; production of cement, brick or building materials such as;(3) R Si, Si and HCl reaction is the reaction of SiHCl3 with hydrogen, by the reaction of the hydrolysis of SiHCl3, IV, and the generation of hydrogen and oxygen in a certain range will explode, so it must be in contact with oxygen and anhydrous conditions,Therefore, the answer is: SiHCl3 hydrolysis, while the production of H2, mixed with O2 explosion, etc.;(4) methanol oxidation reaction, under acidic conditions, methanol in the cathode of carbon dioxide and hydrogen ions, CH3OH+H2O-6e-=CO2+6H+,The answer is: CH3OH+H2O-6e-=CO2+6H+;(5) the significance of this link in industrial production: recycling of raw materials, energy saving and emission reduction,The answer is: recycling of raw materials, energy-saving emission reduction;(6) from P to H3PO4, the phosphorus and oxygen into water and phosphorus pentoxide, compound phosphate, the equation is P+O2=P2O5, P2O5+3H2O=2H3PO4,The answer is: P+O2=P2O5; P2O5+3H2O=2H3PO4
- Q: What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
- Methods for determination of moisture content of coke, a method of introduction of a certain quality of coke samples, placed in a drying box, drying at a certain temperature to a constant quality. Calculation of the percentage of water content in the mass loss of the coke sample. Two. Reagent color silica gel: industrial products
- Q: What are the main uses of coke
- A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas. ??4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
- Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?
- Coal:The use of coal is very extensive, according to the purpose of its use for three main purposes:(1) power coal,(2) coking coal,(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
- Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
- Coke concept:Bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should Have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage
- Q: What is the effect of coke moisture on the blast furnace?
- 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
